MP8864 - Synchronous Step-Down Converter

General Description

The MP8864 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface.

It offers a very compact solution to achieve a 4 A continuous output current with excellent load and line regulation over a wide input supply range.

Key Features

  • include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown (TSD). The MP8864 requires a minimal number of readily available, standard external components and is available in a 15-pin QFN15 (3mm x 3mm) package.

MP8864 High-Efficiency, 4 A, 21 V, Synchronous Step-Down Converter with I2C Interface DESCRIPTION The MP8864 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. It offers a very compact solution to achieve a 4 A continuous output current with excellent load and line regulation over a wide input supply range. The MP8864 has synchronous-mode operation for higher efficiency over the output load range. The reference voltage level is controlled, on-the-fly through a 3.4 Mbps I2C serial interface. The voltage range can be adjusted from 0.6 V to 1.87 V in 10 mV steps. Also, the voltage slew rate, switching frequency, enable, and power-saving mode are selectable through the I2C interface.
